auto posting

We currently have a main company (*blank) and under Blank we have several divisions(companies). We have inter-company transactions that we want to stream line by doing an auto-posting of the AP side. Currently i use ars120 to generate the AR side, this creates an invoice, the AR entry/voucher, and the AP entry/voucher. The AR is working fully; however, the AP voucher is getting stuck in gls047. I have to go there and push the job. The job does not have any error. My user name is a super user in Finance, i have permission to access ARS100, APS100 and all divisions. Any advice on what i am missing so the voucher does not get stuck, Is it a permission to a program? Thanks, C Escobar
